ABSTRACT:
An electronic parking meter system for receiving at least one type of coin or other payment device and including circuits for controlling changeable parameters, such as temperature drift, low voltage levels, aging etc. The electronic parking meter has a power source which may be a solar type power source with a low voltage control circuit. The meter also has a microprocessor with a memory connected to the power supply. The microprocessor has a power-up mode, a standby mode and an operational mode. An electronic display is connected to the microprocessor and displays pertinent information. A coin received in the meter causes a signal to be generated upon receipt of the coin by a sensor. The meter also has a coin detector and a microprocessor controlled circuit for adjusting a setpoint of the coin detector.
